I tried to update the library libssl1.0.0, but it did not help.
How can fix this issue?

Thanks!

The SSL that your system's Python uses might not be compatible with Houdini's. Try setting the environment variable HOUDINI_USE_HFS_PYTHON to 1. e.g.
export HOUDINI_USE_HFS_PYTHON=1
This should make Houdini avoid using the system's python, and use its own.

I have problems with help too very frequently. I'm on windows 7.

What problems? If they seem to be bugs, report them.
The problem that hou.alex.get ran into is pretty specific to Linux. You're likely running into a different issue.

Thank you very much, awong!!! It works!
